摘　　要：目的:研究螺旋CT双期增强扫描对小胰腺癌的早期诊断。方法:25例小胰腺癌患者行螺旋CT胰腺期、肝脏期双期增强扫描,扫描延迟时间分为38 s和70 s,对比剂用量80～100 ml,注射速率3 ml/s。结果:1 cm<病灶<2 cm16例,病灶<1 cm9例,其中属于早期胰腺癌17例。17例早期胰腺癌双期增强病灶均不强化呈低密度,局部无浸润,邻近血管无受侵,无肝脏及远处转移。结论:螺旋CT双期快速扫描依靠胰腺癌的血供特点能够清晰的显示出小胰腺癌与正常胰腺的密度差别,使胰腺癌早期诊断变为现实。Objective：To study the early diagnosis of small pancreatic cancer by dual - phase contrast enhanced spiral CT. Methods.25 cases of small pancreatic cancer were scanned by dual phase contrast enhanced spiral CT, the scan delay time of the Pancreatic phase and Liver phase was 38 s and 70 s respectively. Contrast medium dose was 80 - 100 ml by the injection rate 3 ml/s. Resuits： 16 cases of 1 cm 〈 focus 〈 2 cm ,9 cases of focus（ 1 cm, 17 cases belong to the early pancreatic cancer. All of 17 cases by dual- phase contrast enhanced didnt show enhancement, but showed low density, local lesions and round vascular infiltration didnt appear,hepatic and distant metastases didnt appear too. Conclusions： For the characteristics of vascularization of pancreatic cancer, it may show the difference of lesions and normal pancreas by dual phase contrast enhanced spiral CT, and the diagnosis of small pancreatic cancer became reality.
